CVE-2016-2808

Estado: ModificadaAlta (7.5)—

La implementación de watch en el motor JavaScript en Mozilla Firefox en versiones anteriores a 46.0, Firefox ESR 38.x en versiones anteriores a 38.8 y Firefox ESR 45.x en versiones anteriores a 45.1 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento de generación de contador, acceso a escritura en HashMap fuera de límites y caída de aplicación) a través de un sitio web manipulado.
